1. Security, there is a lot less of a risk when using a Mac that has no security then using a PC that has.
2. Easy to navigate, its just much easier to get to the things you need to get to when your on a mac computer. Well matter fact on any of the apple products.
3. They crash less, they boot up and shut down faster. Since we all live in this fast pace society and get fustrated when our computers crash, many perfer to have something more reliable.
4. Less bulkier.
5. Consistent, when mircosoft does an update, they move things around for no real reasoning behind it. Apple tries to keep the upgrading to minimal and tries to make things easier. Society today, dislikes anything thats really hard for them to do.
6. They write there own operating system, no other company has that
The list can go on and on, but do I really need to say anymore. Look at windows vista, there were so many things wrong with it when it came out, mac has not had that happen since they first came into the market (which was over 30 years ago). Just watch a few of there commercials and you shall see for yourself, why Mac and not a PC. I must say that there commericials are very funny.
